• Refresh your knowledge on less familiar technologies
• Prepare examples of your experience with similar technologies

Example Code Example:

If the job requires experience with React hooks, refresh your knowledge:

jsx

// Example of React hooks usage you might review
import React, { useState, useEffect } from 'react';

function UserProfile() {
  const [user, setUser] = useState(null);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    // Fetch user data when component mounts
    async function fetchUserData() {
      try {
        const response = await fetch('/api/user');
        const userData = await response.json();
        setUser(userData);
      } catch (error) {
        console.error('Error fetching user data:', error);
      } finally {
        setLoading(false);
      }
    }
    
    fetchUserData();
  }, []);

  if (loading) return <div>Loading...</div>;
  if (!user) return <div>No user found</div>;
  
  return (
    <div>
      <h1>{user.name}</h1>
      <p>Email: {user.email}</p>
    </div>
  );
}

// Configure AWS credentials
AWS.config.update({
  region: 'us-west-2',
  accessKeyId: process.env.AWS_ACCESS_KEY,
  secretAccessKey: process.env.AWS_SECRET_KEY
});

// Create S3 service object
const s3 = new AWS.S3();

// Upload a file to S3
async function uploadFile(fileContent, fileName, bucketName) {
  const params = {
    Bucket: bucketName,
    Key: fileName,
    Body: fileContent
  };
  
  try {
    const data = await s3.upload(params).promise();
    console.log(`File uploaded successfully at ${data.Location}`);
    return data.Location;
  } catch (err) {
    console.error("Error uploading file:", err);
